UART close and open(reinit)

Question

Hello, I am using nrf52810 and S112 Softdevice. 
 After initializing uart, use uart close for uart sleep. 
 Then the uart close will be checked. 
 I want to make an uart init and bring it back to life. 
 What is the method? 
 Thank you.

Hi, 
 I cut off uart communication using "app_uart_close()" provided by libraries / uart. 
 I want the action to disconnect the uart and reconnect it. 
 Thank you

PUBLIC void uart_init(void)
{
 U32 err_code;
 UART_CONFIG_t* p_uart = get_uart_config();
 app_uart_comm_params_t const comm_params =
 { 
 .rx_pin_no = p_uart->RX_pin_no,
 .tx_pin_no = p_uart->TX_pin_no,
 .rts_pin_no = p_uart->RTS_pin_no,
 .cts_pin_no = p_uart->CTS_pin_no, 
 .flow_control = p_uart->FlowCtrl,
 .use_parity = p_uart->ParityBit,
 .baud_rate = p_uart->BaudRate
 };

 APP_UART_FIFO_INIT(&comm_params,
 UART_RX_BUF_SIZE,
 UART_TX_BUF_SIZE,
 uart_event_handle,
 APP_IRQ_PRIORITY_LOWEST,
 err_code);
 APP_ERROR_CHECK(err_code);

} 
 This is my uart init code. I can't come back to life if I initialize again.

1.app_uart_close() 2. nrf_drv_uart_uninit(&app_uart_inst); 3. We don't know what the nrf_drv_uart_uninit is doing after that. -> "stopped by vector catch" occurs and does not know where it is going. 
 I don't know what to modify in app_uart_FIFO.....
